I'm using SPSS to create a model of y (dependent variable: 0,11;0,234;0,2324) and five independent variables. I get the following results:
Deviance = 0,20 (value/df); Pearson chi-square = (0,50); Log Likelihood = -200,454; Omnibus test: Likelihood ratio chi-square - sig = 0.000.
According with SPSS, this last test indicates that this model overcomes the null model. What does it means?
Should I calculate pseudo R^2?
I'm new in this kind of models, so it's hard for me to interpret them. I found some articles, but they all about Poisson distribution.
PS: if you know about any useful books, I appreciate!
